Welder’s Test Position (ASME IX QW-461.3-461.7)

2G – Horizontal Position. Plate in a vertical plane with the axis of the weld horizontal

3G – Vertical Position. Plate in a vertical plane with the axis of the weld vertical

4G – Overhead Position. Plate in a horizontal plane with the weld metal deposited from underneath

Groove Welds in Pipe – Test Positions

1G (rotated) – Flat Position. Pipe with its axis horizontal and rolled during welding so that the weld metal is deposited from above

2G – Horizontal Position. Pipe with its axis vertical and the axis of the weld in a horizontal plane. Pipe shall not be rotated during welding

5G – Multiple Position. Pipe with its axis horizontal and with the welding groove in a vertical plane. Welding shall be done without rotating the pipe

6G – Multiple Position. Pipe with its axis inclined in 45 degrees to horizontal. Welding shall be done without rotating the pipe.

Fillet Welds in Plate – Test Positions

1F – Flat Position. Plates so placed that the weld is deposited with its axis horizontal and its throat vertical.

2F – Horizontal. Plates so placed that the weld is deposited with its axis horizontal on the upper side of the horizontal surface and against vertical surfacde.

3F – Vertical Position. Plates so placed that the weld is deposited with its axis vertical.

4F – Overhead Position. Plates so placed that the weld is deposited with its axis horizontal on the underside of the horizontal surface and against the vertical surface.

Fillet Welds in Pipe- Test Positions

1F (rotated) – Flat Position – Pipe with its axis incline at 45 degrees to horizontal and rotated during welding so that weld metal is deposited from above and at the point of deposition the axis of the weld is horizontal and the throat vertical

2F – Horizontal Position. Pipe with its axis vertical so that the weld is deposited on the upper side of the horizontal surface against the vertical surface. The axis of the weld will be horizontal and the pipe is not rotated during welding

2FR – Horizontal Position (Rotated). Pipe with its axis horizontal and the axis of the deposited weld in the vertical plane. The pipe is rotated during welding.

4F – Overhead Position – Pipe with its axis vertical so that the weld is deposited on the underside of the horizontal surface against the vertical surface. The axis of the weld will be horizontal and the pipe is not rotated during welding.

5F – Multiple Position. Pipe with its axis horizontal and the axis of the deposited weld in the vertical plane. The pipe is not rotated during welding.
